<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I am not aware of any prevailing python utils for this. An alternative is to shell out Linux commands to collect the information. After a quick search, it looks
xenapi [1] uses “lspci -vmmnk” to collect PCI device detail info and “ls /sys/bus/pci/devices/<pci_device>/” to detect the PCI device type (PF or VF). FWIW, you might find it helpful to refer the implementation of Nova’s xenapi driver for gettiing PCI resources
[2]. Hope it helps.<o:p></o:p></span></p>

<p class="MsoNormal">For <a href="https://blueprints.launchpad.net/zun/+spec/support-pcipassthroughfilter">https://blueprints.launchpad.net/zun/+spec/support-pcipassthroughfilter</a> this BP, Nova use the libvirt to collect the PCI device info. But for zun,
libvirt seems is a heavy dependecies. Is there a python utils that can be used to collect the PCI device detail info? Such as the whether it's a PF of network pci device of VF, the device capabilities, etc.<o:p></o:p></p>
